STATEMENT REGARDING FEDERALLY-SPONSORED RESEARCH AND DEVELOPMENT

None.

Latin name of the genus and species: Genus—Vaccinium.Species—corymbosum.

VARIETY DENOMINATION

The new blueberry plant claimed is of the variety denominated‘ZF08-029’.

BACKGROUND OF THE INVENTION

The present invention relates to the discovery of a new and distinctcultivar of northern highbush blueberry (Vaccinium corymbosum L. hybrid)plant, referred to as ‘ZF08-029’, as herein described and illustrated.‘ZF08-029’ is a commercial blueberry variety intended for both the freshand processed fruit markets. The variety has high plant vigor, asemi-sprawling, rounded growth habit, ripens mid-season, and producesmedium sized fruit with good firmness. ‘ZF08-029’ was selected for itsabove average fruit quality, specifically its highly aromatic, peachtype flavor.

‘ZF08-029’ has a more rounded and vigorous growth habit, and moreflavorful, though smaller, fruit than ‘Draper’ (U.S. Pat. No. 15,103),the male parent. Compared to the female parent ‘G-344’ (not patented),‘ZF08-029’ appears to be more tolerant to cold temperatures.

Pedigree and History: The new blueberry plant originated from a cross of‘G-344’ (female parent, not patented) and ‘Draper’ (male parent) made inLowell, Oreg., USA in 2004 and was selected in the same location in2008.

The new blueberry variety ‘ZF08-029’ was initially propagated bysoftwood cuttings in 2008 from the original seedling in Lowell, Oreg.,USA and planted in a replicated plot of nine plants in fall 2009. Theplants established in Oregon were successfully used to establish invitro culture lines in 2012

‘ZF08-029’ was selected in 2008 because of its high-quality fruit—firm,crisp, peachy flavor, light blue color, and medium size. Beginning in2011, ‘ZF08-029’ was evaluated for seven years in Lowell, Oreg. forplant performance, fruit quality, and yield in comparison to standardvarieties like ‘Legacy’ (not patented) and ‘Draper’ . Beginning in 2012,additional plots of ‘ZF08-029’ were established in other areas ofOregon, Northwest Washington and Central California. After extensiveevaluation in these growing regions, ‘ZF08-029’ was determined to besufficiently cold hardy and adaptable to varying soil conditions andcommercial management strategies, and has a competitive yield for theharvest season. Plants of ‘ZF08-029’ propagated from softwood cuttingsor in vitro are phenotypically stable and exhibit the samecharacteristics as the original plant.

SUMMARY OF THE INVENTION

The new blueberry plant variety ‘ZF08-029’ has not been observed underall possible environmental conditions. The phenotype may vary somewhatwith variations in environment and cultural practices such astemperature and light intensity without, however, any variance ingenotype.

‘ZF08-029’ is distinguished by a rounded, semi-sprawling growth habit,high vigor, and complex fruit flavor. The following characteristics ofthe new cultivar have been repeatedly observed and are determined to bethe unique characteristics of the new blueberry plant variety‘ZF08-029’:

1) Mid-season ripening

2) Medium, uniform fruit size

3) Aromatic, flavorful fruit with a firm texture

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctivecharacteristics of ‘ZF08-029’. The data which define thesecharacteristics were collected from asexual reproductions of theoriginal selection. Dimensions, sizes, colors, and other characteristicsare approximations and averages set forth as accurately as possible. Theplant history was taken on plants approximately 5 years of age, unlessotherwise noted, and the descriptions relate to plants grown in thefield located at 39252 Jasper-Lowell Road, Lowell, Oreg., USA.Descriptions of fruit characteristics were made on fruit grown at thefield described above. Color designations are from “The Pantone Book ofColor” (by Leatrice Eiseman and Lawrence Herbery, Harry N. Abrams, Inc.,Publishers, New York 1990). Where the Pantone color designations differfrom the colors of the photographs, the Pantone colors are accurate.
